Switchgear
Switchgears receive electricity at the specified voltage, increase or lowers the voltage, and distribute electricity to respective loads to supply electricity safely. They are stored in a metallic enclosure so that they can be used safely over the long term. They are equipped with switches for operating equipment, meters for measuring voltage and current, etc., and protection relays for detecting abnormalities, among other instruments.
